22a58f5420 Swap alpm_db_update() implementation to multiplexed version
Now when all callers of the old alpm_db_update() function are gone we can
remove this implementation. And then rename alpm_dbs_update() function to
alpm_db_update().

b96e0df4dc Implement multibar UI
Multiplexed download requires ability to draw UI for multiple active progress
bars. To implement it we use ANSI codes to move cursor up/down and then
redraw the required progress bar.
`pacman_multibar_ui.active_downloads` field represents the list of active
downloads that correspond to progress bars.
`struct pacman_progress_bar` is a data structure for a progress bar.

In some cases (e.g. database downloads) we want to keep progress bars in order.
In some other cases (package downloads) we want to move completed items to the
top of the screen. Function `multibar_move_completed_up` allows to configure
such behavior.

Per discussion in the maillist we do not want to show download progress for
signature files.

c78eb48d91 Extend download callback interface with start/complete events
With the previous download interface the callback uses the first progress
event as 'download has started' signal. Unfortunately it does not work with
up-to-date files that never receive 'download progress' events.
Up-to-date database messages are currently handled in sync_syncdbs()
after the sequential download is completed and a result from ALPM is
received. But this is not going to work with multiplexed download
interface that returns the result only after all files are completed.

Another problem with 'first progress event is the beginning of the
download' is that such events time are unpredictable. Thus the UI progress
bar order might differ from what has been passed by client to
alpm_dbs_update() function. We actually want to keep the dbs progress bars
in a strict order.

To help to solve the given problems extend the download callback to
allow 2 more events - download started and completed. 'Download started'
events appear in the same order as in the list given by a client.

64c4669f57 Introduce event types for start/end database list download
Multiplexed database/files downloads will use multiple progress bars.
The UI logic is quite complicated and printing error messages while
handling multiple progress bars is going to be challenging.

Instead we are going to save all ALPM error messages to a list and flush
it at the end of the download process. Use on_progress variable that
blocks error messages printing.

6a331af27f Implement multiplexed download using mCURL
curl_multi_download_internal() is the main loop that creates up to
'ParallelDownloads' easy curl handles, adds them to mcurl and then
performs curl execution. This is when the paralled downloads happens.
Once any of the downloads complete the function checks its result.
In case if the download fails it initiates retry with the next server
from payload->servers list. At the download completion all the payload
resources are cleaned up.

curl_multi_check_finished_download() is essentially refactored version of
curl_download_internal() adopted for multi_curl. Once mcurl porting is
complete curl_download_internal() will be removed.

dc98d0ea09 Add multi_curl handle to ALPM global context
To be able to run multiple download in parallel efficiently we need to
use curl_multi interface [1]. It introduces a set of APIs over new type
of handler 'CURLM'.

Create CURLM object at the application start and set it to global ALPM
context.

The 'single-download' CURL handle moves to payload struct. A new CURL
handle is created for each payload with intention to be processed by CURLM.

Note that curl_download_internal() is not ported to CURLM interface due
to the fact that the function will go away soon.

a8a1a1bb3e Introduce alpm_dbs_update() function for parallel db updates
This is an equivalent of alpm_db_update but for multiplexed (parallel)
download. The difference is that this function accepts list of
databases to update. And then ALPM internals download it in parallel if
possible.

Add a stub for _alpm_multi_download the function that will do parallel
payloads downloads in the future.

Introduce dload_payload->filepath field that contains url path to the
file we download. It is like fileurl field but does not contain
protocol/server part. The rationale for having this field is that with
the curl multidownload the server retry logic is going to move to a curl
callback. And the callback needs to be able to reconstruct the 'next'
fileurl. One will be able to do it by getting the next server url from
'servers' list and then concat with filepath. Once the 'parallel download'
refactoring is over 'fileurl' field will go away.

means an upstream source could be maliciously changed and passed on as valid

d626a17ef9 makepkg: make per-package files containing '$pkgname' consistently work
Extracting function variables containing arbitrarily scoped variables of
arbitrary nature is a disaster, but let's at least cover the common case
of using the actual '$pkgname' in an install/changelog file. It's the
odd case of actually being basically justified use of disambiguating
between the same variable used in multiple different split packages...
and also, --printsrcinfo already uses and overwrites the variable
'pkgname' in pkgbuild_extract_to_srcinfo, so this "works" in .SRCINFO
but doesn't work in .src.tar.gz

It doesn't work in lint_pkgbuild either, but in that case the problem is
being too permissive, not too restrictive -- we might end up checking
the same file twice, and printing that it is missing twice.

2e32d51a26 Remove unneeded ltmain patch
Many moons ago, libtool was bad - I mean worse than today!  It gobbled all
--as-needed and we ended up with an overlinked libalpm.  This was annoying,
particularly when dealing with soname bumps in libraries pacman/libalpm had
no business linking to. Luckily we had a fix, stolen from GNOME I believe.
And with that fix, we lived in harmony with libtool for many years.  Until one
day, unbeknownst to us, libtool was "fixed".  We kept applying our patch,
because it still applied, but it did worse than nothing.  It gobbled up our
other LDFLAGS, and our libalpm started missing out on RELRO and BIND_NOW.
This made the Arch Security Team unhappy. We will make them happy again by
